With respect to anomaly detection and setting inferred fields for a float type scalar encoded input, what is the difference in the quality of anomaly scores on using SDRClassifier versus CLAClassifier?

What kind of situation/use case calls for the usage of one over the other?

They are the same. We renamed the `CLACassifier` to `SDRClassifier`.
